  • Need size of STOCK tanks for 2016 GenII-x30 for surf config?

    OK, this has probably been answered somewhere - but I can seem to find a consistent answer.

    What size and are the STOCK tanks in the 2016 Gen II ballast for the x30? Then what number do you use per gallon to calculate pounds?

    Keel -
    Starboard and port back hard tanks -
    Starboard and port back soft tanks -

    Reading and digging through lots of good information on this forum. Trying to come up with a good surf setting. I was using all tanks full - and dropping the tab on the opposite side we would ski on. Happy with output, however we added a wake shaper and WOW what a difference took what we had and added about 5 feet!!

    Now I have been reading to run all tanks empty except the side you are going to be on. Crazy - anyone tried that?

    Thanks in advance!!

    Don't know tank size but water weighs 8.33 pounds per gallon.

      Gen2 is 1920 lbs. 710 on each side, 500 in the middle. The purpose of the Gen2 system was to take the guessing out of it. Weight the boat evenly and deploy opposite side tab, middle also for port side surfing.
      There may be better ways to relax than being on a boat...I just haven't found one yet!

        Just a heads up, these numbers include the bags that sit on top of the tanks at the back. So if you are looking for the weight of just the tank, subtract I believe 400, hopefully someone can confirm.

          I was pretty sure they were 400 lb bags but not 100%. That's prolly about right.

            Do you have pics with and without the wake shaper?

              I agree! after lots of testing. I have a 2017 XT23 basically same thing.

              With no extra weight and not many people in the boat I wasn't getting any push. I tried letting water out of starboard and putting that tab down more( i surf normal side) and all kinds of things.

              What I found out also is make sure your tab is deploying, you might have a bad actuator and it might say 65% but actually be at 75% or more who knows. I have had mine replaced one all ready and they might be be going out again.

              This is what is working for me right now with stock ballast full!! Left steep setting which should be 30% and 65%. Once in motion or preset if you have the big screen, set them to 0% center tab and 50% starboard and I get a really huge wave with only 2 adults. I go about 10.3 to 10.6 mph. If I have the boat full of people then the stock preset works fine.

              angle of pic not great but only two adults in the boat and I have my son on the board. I am pretty far back as well.

                Thanks for the information.

                So we have 710 per side / 400 / 310 and 500 for the keel. 1920 total. That is what I was looking for.

                I was wanting to run some test this weekend with some different configs.

                I'll get some pics for your all and let you know what is the best set up.

                Again - goofy side my setting:
                All tanks 100%
                Port tab 100
                Center tab 10
                Starboard tab 0
                Wake shaper on opposite side

                Going to try - taking the center tank down to 50 and the port side tank between 50 and 0. Also with less tabs (75 and 50%).

                We will see!!

                Mastercraft talks about having "4 zones" for surfing. I feel I get 1 and 2 - but want 3 and 4.

                    In my head the bags were 400 or the tanks were 400, so if you were thinking 400 for bags, we're probably right; that was my inclination as well.

                      I'm looking forward to seeing your pics with and without the wave shaper using the stock settings (all tanks full and 100% tab on opposite side). We switch sides too often to be messing around with filling/dumping ballast, but moving the wave shaper from side-to-side is doable if it made a noticable difference.

                        I’ll just go ahead and say it - you’re doing it wrong if you need to use less ballast or a wake shaper with a Gen2 X30.

                        1100 lb sacks, 400 lbs lead, surf right steep (100% port), 11.1 mph, no suckgate.

                          100% agree! If there is one thing these boats like it’s extra weight.

                            So you have 1100lbrs in the lockers?

                            Where did you put your lead?

                              Yes, the X30 lockers allow 1100 lb. sacks and the X10 permit 820 lb. bags. IIRC, the XT23 lockers are smaller as their subfloor ballast is greater than the prior generation X30”s.

                              X30 Surf Vid thread: https://teamtalk.mastercraft.com/showthread.php?t=86489

                              We distribute lead 100 lbs bow, 150 lbs under observer seat, 100 surf corner, 50 opposite corner. If running full crew may take out some or all of the lead and bump up speed further. Rule of thumb is to get swim platform just touching surf wave corner and add or delete upfront and add speed to adjust to this.

                              Wakemakers gurus will tell you to slam stern to get best wave size, slam the surf corner to the rub rail for shape, and add ballast amidships and fore to lengthen wave. Human ballast is free to test this theory.

                              IME, none of the Gen2 boats will benefit from less weight or a suckgate. If anything, the arms race of larger/wider/taller boats will require increasingly more ballast to create great surf waves. Our X10 kicks it as it needs less ballast to displace the hull for a great surf wave.
